[PATCH v15 002/115] KVM: x86/vmx: initialize loaded_vmcss_on_cpu in vmx_hardware_setup()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Isaku Yamahata <isaku.yamahata@xxxxxxxxx>

vmx_hardware_disable() accesses loaded_vmcss_on_cpu via
hardware_disable_all().  To allow hardware_enable/disable_all() before
kvm_init(), initialize it in vmx_hardware_setup() so that tdx module
initialization, hardware_setup method, can reference the variable.
